Mounting system for arranging electric devices, for example, especially in switchgear cabinets

ABSTRACT

The invention relates to a mounting system ( 1 ) for arranging electric devices ( 2 ), for example, especially in switchgear cabinets. Said mounting system ( 1 ) comprises at least one preferably horizontal mounting strip ( 3 ) to which at least one device ( 2 ) can be secured. At or near at least one of its longitudinal edges, the mounting strip ( 3 ) includes a receiving device ( 20 ) which extends along the longitudinal axis of the mounting strip ( 3 ) and into which additional components ( 7, 8, 9, 10, 11 ) of the mounting system ( 1 ) can be inserted, e.g. ordering means ( 7, 8, 9, 11 ) for ordering the connecting wires ( 34, 35 ) of the device ( 2 ) that is to be secured to the mounting strip ( 3 ). The invention is characterized in that the receiving device ( 20 ) has at least one locking means ( 22, 23 ) that is to be interlocked with an associated locking means ( 26 ) of the additional component ( 7, 8, 9, 10, 11 ) of the mounting system ( 1 ) that can be inserted into the receiving device ( 20 ), and in that depending on the design of the associated locking means ( 26 ) of the additional component ( 7, 8, 9, 10, 11 ), the interlocking action can be cancelled exclusively by a pulling force acting on the additional component ( 7, 8, 9, 10, 11 ) or cannot be cancelled but is self-locking.

The invention relates to a mounting system for the arrangement of electrical devices, for example in particular in switchgear cabinets.

In the field of industrial control technology, electrical devices are frequently disposed in switchgear cabinets or switch boxes. The individual devices are disposed on mounting rails, for example such as a top-hat rail, and may be connected with one another in series. The devices are subsequently hard-wired, wherein a comb-shaped ordering means is mounted on the mounting strip exhibiting the mounting rail in order to order the connecting wires of the devices. An associated mounting system is offered by the applicant, Friedrich Lütze GmbH in 71384 Weinstadt, and is known, for example, from DE 297 16 229 U1 or also DE 20 2008 015 309 U1.

DE 198 59 606 A1 presents a quick-assembly wiring system comprising a supporting structure for attaching the devices and device islands having top hat rail-like mounting rails that can be attached to the supporting structure.

The object of the present invention is to provide a mounting system that has improved performance characteristics, in particular such that it is versatile in its use and in so doing, is nevertheless easy to use and to install. In one embodiment, the mounting system is intended to increase the operational reliability of the devices attached thereto and further increase the flexibility in ordering the connecting wires of the devices.

This object is achieved by the mounting system specified in Claim 1. Specific embodiments of the invention are identified in the dependent claims.

In one embodiment, the mounting system has at least one preferably horizontal mounting strip, on which at least one device can be mounted. The mounting strip has a receiving device on or near at least one longitudinal edge of said mounting strip, which receiving device extends along the longitudinal axis of the mounting strip, into which the additional components of the mounting system can be inserted, for example ordering means for ordering the connecting wires of the device that is to be mounted on the mounting strip, in particular, so-called cable combs.

The receiving device has at least one locking means that is to be interlocked with a corresponding locking means of the additional component of the mounting system that can be inserted into the receiving device. Depending on the design of the corresponding locking means of the additional component, the interlocking action can be cancelled exclusively by a pulling force applied to the additional component, or cannot be canceled but rather, is self-locking.

It is advantageous that this is determined solely by the design of the corresponding locking means of the additional component, because in this way, using the same mounting strip, it is possible to determine by the additional component alone whether it is possible to cancel the interlocking action exclusively by means of a pulling force, or whether this is not possible, in particular, whether this can be achieved without tools, or whether it is only possible through the use of a tool. In this way, for example, it is possible to permanently mount a first additional component at a critical location, for example an edge protector for electrical lines, at those locations at which electrical lines with hazardous operating voltages are guided. On the other hand, at non-critical locations, it is possible to use interlocking action to install additional components on the receiving device such that that the interlocking action can be canceled, for example segments of a cable comb.

In the case of the mounting system, one or a plurality of mounting strips, in particular mounting strips that run parallel to one another, may be affixed on a support device, for example on profile bars that that extend at a right angle to the mounting strips and are preferably vertical, which profile bars, together with the mounting strips, form a mounting frame, which can be pre-assembled and subsequently installed, for example in a switchgear cabinet.

In one embodiment, the locking means of the receiving device is formed by a locking flank that extends in the longitudinal direction of the mounting strip, and that is integrally formed as a component of the mounting strip. The mounting strip may be formed by a profile bar that has been cut to length and can be manufactured out of aluminum or an alloy that contains aluminum. In this way, a mechanically stable locking flank can be formed, having a high degree of freedom of design.

In one embodiment, the locking flank is disposed on the exterior of the receiving device facing away from the front side of the mounting strip on which the device can be mounted. The locking flank is not accessible thereby from the front side or in any event, is not easily accessible, which is advantageous in order to reliably prevent an unintentional release of the locking connection when working on the mounting system.

The self-locking locking mechanism may be provided for additional components that are subjected to a heavy mechanical load, for example for cable combs for large connecting wires. Accordingly, these additional components may also be such that they are not self-locking but rather, if applicable may be also be released without tools, for example cable combs for connecting wires having a small diameter.

In one embodiment, the receiving device comprises a groove that extends in the longitudinal direction of the mounting strip, and that is positioned at a right angle to the longitudinal axis in the longitudinal edge of the mounting strip, into which groove a strip-shaped connecting section of the additional component of the mounting system that is preferably cylindrical in the longitudinal direction thereof can be inserted. The groove may have a surface texture on the inner surface thereof, in particular channels that extend in the longitudinal direction thereof, in order to prevent an unintended clamping and thereby to ensure a simple actuation.

In one embodiment, the locking means of the receiving device is formed on the outside of a wall that is adjacent to the groove. In this way, the additional component can form a locking flank surrounding the groove with reduced material usage and therefore reduced dimensions, said locking means being integrally formed on the strip-shaped connecting section of the additional components.

In one embodiment, the mounting system has components of the first kind, which have a corresponding locking means having a locking flank of the first kind, which, together with the direction of the pulling force, forms an angle that is greater than 90° and as a result, the interlocking action can be canceled exclusively by a pulling force. The direction of the pulling force is thereby parallel to the direction in which the additional component is inserted into the groove of the receiving device.

In one embodiment, the mounting system has components of the second kind, which have a corresponding locking means having a locking flank of the second kind, which, together with the direction of the pulling force, forms an angle that is less than 90° and as a result, the interlocking action cannot be canceled exclusively by a pulling force but rather, the locking force is self-locking. When pulling, there is positive locking of the corresponding locking means of the receiving device on one hand, and the additional components of the second kind on the other hand, so that in any event, a non-destructive release of the additional component of the second kind is not possible without additional measures.

In one embodiment, the receiving device has both a first locking means for the interaction with a corresponding locking means of an additional component of the first kind of the mounting system, that can be released exclusively by a pulling force, as well as a second locking means for the interaction with a corresponding locking means of an additional component of the second kind of the mounting system, that cannot be canceled exclusively by a pulling force but rather, is self-locking. The first locking means preferably has a smaller spacing from the opening of the receiving device into which the additional components are inserted than does the second locking means.

In one embodiment, the mounting system has an edge protector element as an additional component, by means of which the receiving device and therefore the free end of the mounting strip, as well, can be covered, and thus damage to a connection line at the end of the mounting strip can be prevented. Preferably at least a section of the edge protector element has a convex surface, wherein the curvature preferably extends over an angular range greater than 90°, in particular greater than 135° and preferably approximately 180°.

The devices may be electrical devices, for example power supplies, fuses, control units, input/output components, interface units, temperature converters, analog/digital transducers or the like. Alliteratively or in addition, the device may also have non-electrical components, for example optical components or pneumatic components.

FIG. 1 shows a perspective view of an embodiment of a mounting system 1, which has a total of four horizontal mounting strips 3, 103, on each of which at least one device 2 (FIG. 17) can be mounted. The two lower mounting strips 103 have a smaller lateral extension as compared to the two upper mounting strips 3. The mounting strips 3, 103 are each connected with a vertical profile bar 4 at or near the ends of each, for example up to 200 mm and in particular up to 125 mm from the two ends, in each case by means of a mounting bracket 5 or another connection element 79 (FIG. 31) and together with the profile bars 4, form a mounting frame, which can be pre-assembled and subsequently installed in the condition depicted in FIG. 1, or which can also be used together with devices 2 that have already been mounted there and with the connecting wires 34, 35 (FIG. 5) thereof in a switchgear cabinet. The mounting strips 3, 103 each have a mounting rail 6, on which the devices 2 are to be mounted, which in the case of the embodiment, is a standard top-hat rail or that essentially corresponds to a standard, having a top-hat rail height of 7.5 mm.

An ordering means 8 is affixed at the longitudinal edges of each of the upper mounting strip 3 in FIG. 1, said ordering means comprising a plurality of ordering segments 7 having an identical design. Individual or a plurality of ordering segments 7 can optionally be released from the ordering means 8 and removed from the ordering means 8 or, respectively, the mounting strip 3 while leaving a gap in their place, or may be replaced by another ordering segment 9 (FIG. 2), 11 (FIG. 3) or a group of ordering segments 9, 11.

FIG. 2 shows a mounting strip 3 in an enlarged scale. FIG. 3 shows an ordering means 108, which comprises a plurality of integrally formed ordering segments 11, which are disposed one behind the other. Instead of the integral design, the ordering segments 11 may also have a linking means at each of their ends, by means of which the ordering segments 11 can be releasably linked with one another. The ordering means 108 may be manufactured in predetermined lengths, for example approximately 1 m or 2 m, or may be manufactured as a continuous strip.

Each ordering segment 11 has a strip-shaped fastening section 12, which can be inserted into a receiving device 20, said receiving device being disposed at the longitudinal edges of the mounting strip 3 and having a groove 13 (FIG. 7). A groove 14 that extends in the direction of insertion is centrally positioned in the fastening section 12 with respect to the longitudinal extension, whereby it continues to be possible to access the end of this groove that forms a tool contact surface when in the inserted state and into which it is possible to introduce a tool 33 (FIG. 4) in order to release the ordering segment 11.

Integrally formed, together with the fastening section 12, the ordering segment 11 preferably forms resiliently deflectable ordering elements 15, between which, connecting wires 34, 35 of the device 2 can be inserted and thereby affixed in an ordered manner. Intended separation points 16, at which the ordering segments 11 can be separated, are formed by cuts in the fastening section 12. The cuts thereby extend beyond a stop edge 17 formed by the ordering segment 11, up to which stop edge the ordering segment 11 can be inserted into the groove 13. The position of the intended separation point 16 is thereby also visible in the inserted state. A separating cut can be made in the direction of the ordering elements 15.

The ordering segment 9 has two receiving chambers 18 for the connecting wires 34, 35 that are to be ordered, which chambers each extend over half the length of the ordering segment 9. Two brackets 19 of the ordering segment 9, which face the mounting strip 3 or, respectively, the fastening section 12, are made resiliently deflectable for the insertion of the connecting wires 34, 35 that are to be ordered into the receiving chamber 18.

By contrast, the ordering segment 7 has a plurality of ordering elements 115, of which there are five in the embodiment, each of which has an elastically deformable hook section for closing the receiving chamber 118. Additional ordering segments may also have differently designed receiving chambers 18, 118, in particular differently sized receiving chambers 18, 118, for example one or a plurality of larger receiving chambers 18 that are identical or similar to the ordering segment 9, and one or a plurality of smaller receiving chambers 118 that are identical or similar to the ordering segment 7. In one embodiment, the longitudinal extension of the individual receiving chambers 18, 118 is at least 5%, in particular at least 8% and preferably at least 10% of the total longitudinal extension of the ordering segment 7, 9. In the case of the additional component 10 of the mounting system 1, this additional component is an edge protector element. The ordering segments 7, 9, like the additional component 10, have matching lengths, which is 50 mm in the embodiment.

FIG. 4 shows a perspective view of a mounting strip 103 having an ordering means 108, which is formed by stringing together ordering segments 11, and which is inserted into the groove 13. An ordering segment 11 is thereby separated by two cuts at the intended separation points 16, and by inserting a tool 33, for example the blade of a flat-bladed screwdriver, the separated ordering segment 11 can be released from the mounting strip 103 and removed.

FIG. 5 shows a perspective view of the mounting strip 103 from FIG. 4, wherein instead of the ordering segment 11 released in FIG. 4, an ordering segment 9 having two large receiving chambers 18 has been inserted, in which chambers a bundle of connecting wires 34 or, respectively, a connecting line 35 having a large diameter, has been inserted.

The ordering segment 9 has a retaining section 36 which projects transversely to the longitudinal direction, in particular, which projects on the front side of the mounting strip 103 having the mounting rail 6 for better fixation of the connecting wires 34, 35. The ordering segment 9 has a retaining section 36 for each receiving chamber 18. The retaining section 36 has a T-shape formed at each free end thereof for better fixation of a fastening means 3 7, which may be a cable tie.

FIGS. 6, 9 and 12 show the ordering segments 7, 9 as well as the additional component 10 in one view. The ordering segment 9 and the additional component 10 can be permanently affixed to the mounting strip 3, which is why these components 9, 10 have no tool contact surface 14.

FIG. 7 shows a section through a mounting strip 103 having the ordering segment 7 attached thereto. FIG. 8 shows a detail from FIG. 7 in the region of the connection of the ordering segment 7 with the mounting strip 103 in an enlarged scale. In addition to the groove 13, the side walls of which have a plurality of additional grooves 21 or corrugations that extend in the longitudinal direction of the mounting strip 103, the receiving device 20, which extends along the longitudinal axis of the mounting strip 103 and which is integrally formed as a component of the mounting strip 103, into which receiving device the ordering segment 7 can be inserted, has two locking flanks 22, 23 on an outer face of said receiving device 20, which locking flanks extend in the longitudinal direction of the mounting strip 103 and are integrally formed as a component of that mounting strip. In particular, the two locking means 22, 23 are formed on the outside of a wall 24 that is adjacent to the groove 13, said wall being set back in a lateral direction as compared to the facing wall 25 that likewise is adjacent to the groove 13. On the outside, the wall 24 has a surface that extends obliquely to the direction in which the ordering segment 7 is inserted and in particular, obliquely to the groove 13. The oblique position makes it possible to deflect the locking means 26 while inserting ordering segment 7 with less force.

The ordering segment 7, which forms a component of the first kind of the mounting system 1, has a corresponding locking means 26, which is formed by a bracket that, in the undeformed starting state, extends nearly parallel to the fastening section 12, but that is resiliently deflectable with respect thereto, whereby a locking flank 27 of the first kind is formed near the free end of said flank, which locking flank, together with the direction 28 of the pulling force, forms an angle 29 that is greater than 90° and as a result, the interlocking action can be canceled exclusively by a pulling force. For ease of handling, the release force can be applied by a flat-bladed screwdriver 33, which can be inserted into the tool contact surface 14.

FIG. 10 shows a section through a mounting strip 103 having the ordering segment 9 attached thereto. FIG. 11 shows a detail from FIG. 10 in an enlarged scale in the region of the connection of the ordering segment 9 with the mounting strip 103. The ordering element 9 forms a component of the second kind of the mounting system 1 with a corresponding locking means 126, which has a locking flank 30 of the second kind, which, together with the direction 28 of the pulling force, forms an angle that is less than 90° and as a result, the interlocking action cannot be canceled exclusively by a pulling force but rather, is self-locking. Accordingly, the ordering element 9 is affixed to the mounting strip 3 with a high degree of stability, corresponding to the large receiving chambers 18 for the insertion of large and heavy connecting wires 34, 35.

FIG. 13 shows a section through a mounting strip 103 having an additional component 10 affixed thereto. FIG. 14 shows a detail from FIG. 13 in an enlarged scale in the region of the connection of the additional component 10 with the mounting strip 103. In the case of the additional component 10, this is an edge protector element, whereby the surface of said edge protector that faces away from the mounting strip 103 has a convex surface 32, which extends over an angular range of 180°, however which deviates from a circular shape. The additional component 10 may be manufactured as an extrusion part made out of plastic, for example, and may be individually cut to the desired length. The additional component 10 does not have a tool contact surface 14, so that, while in principle it is possible to cancel the interlocking action through a pulling force in direction 28, due to the material used and the structural design, this cannot be done manually or can be done only with great effort. This is intended to prevent the additional component 10 from being unintentionally released from the mounting strip 103.

In one embodiment, in those ordering segments 7, 11 or components in which the tool contact surface 14 is visible when mounted on the mounting strip 3, 103, the interlocking action is not self-locking but rather, can be canceled exclusively by a pulling force: in particular, those ordering segments 7, 11 have a locking means 26 having a locking flank 27 of the first kind, by means of which the interlocking action can be canceled exclusively by a pulling force.

FIGS. 15 and 16 show a side view of a mounting strip 203 according to the prior art or, respectively, a control panel 303 according to the prior art, which each have a mounting rail 6 having a height of 7.5 mm, for example. Due to the relatively low height of the mounting rail 6, devices 2 having a comparatively higher design height cannot be affixed but rather at best, only those devices 102 that have a reduced design height on at least one side can be affixed. In order to solve the problem so that large devices 2 could also be affixed in the case of mounting rails 6 having a comparatively low design height, in addition to a first, preferably central section 41, in which the mounting rail 6 is also formed, a mounting strip 3 that is preferably designed such that it is symmetrical to a middle plane 40 has a third section 43 that is spaced apart from the mounting rail 6, which third section has a greater vertical distance 44 from the base point 39 of the mounting rail 6 than a second section 42, which is disposed between the first section 41 and the third section 43 at the end that is near the mounting rail 6, in particular, adjacent to the mounting rail 6.

In the embodiment in FIGS. 17 and 18, this is achieved by means of a convex curvature of the mounting strip 3, in particular in the second section 42 thereof. The convex curvature extends over an angular range of approximately 15°, and the radius of the convex curvature is approximately four times the lateral extension of the curved second section 42. The vertical distance 44 between an end of the second section 42 that faces the third section 43 and an end of the second section 42 that faces the first section 41 thereby approximately corresponds to the height 45 of the mounting rail 6, so that the total height 46 for attaching the device 2 on the mounting rail 6 is approximately double the height 45 of the mounting rail 6. As FIGS. 17 and 18 show, despite the relatively low height 45 of the mounting rail 6, devices 2 having a larger structural form can be easily affixed to the mounting strip 3.

FIG. 19 shows a perspective view of a mounting strip 403. FIG. 20 shows a side view of a mounting strip 403 from FIG. 19. FIG. 21 shows a detail from FIG. 20 in an enlarged scale in the region of a groove 47 that is integrally formed as a component of the mounting strip 403 for the releasable insertion of identification plates 48 using an interlocking action. The groove 47 thereby has an undercut 49 on both sides, into each of which a resiliently deflectable bracket 50 of the identification plate 48 engages with an interlocking action. The groove 47 is disposed in the region of the third section 43 of the mounting strip 403 or in an end of the second section 42 of the mounting strip 403 that is removed from the first section 41. This ensures that the identification plate 48 can be read, even when a device 2 is affixed to the mounting strip 403. The identification plate 48 may identify a connecting line 35, 36 that is run adjacent to the identification plate 48 from the reverse side to the front side of the mounting strip 403, for example, or may identify a device 2 that is disposed on the mounting rail in the region of the identification plate 48.

Ordering means 8 or additional components 10 of the mounting system 1 may be installed in the receiving device 120 and in particular, may be inserted into the insertion groove 113. At least one of the walls that are adjacent to the insertion groove 113 has one or a plurality of depressions 51 or corrugations that preferably extend in the longitudinal direction of the insertion groove 113, for example for the non-releasable interlocking action of a component of the mounting system 1 that can be inserted into the receiving device 120 or, respectively, into the insertion groove 113. Externally, the receiving device 120 also has a first locking flank 22 and a second locking flank 23, wherein the first non-inhibiting locking flank 22 has a smaller spacing from the free end of the receiving device 120 as compared to the inhibiting second locking flank 23.

FIG. 22 shows a perspective view of an end of the mounting strip 3 having the connection with the mounting bracket 5. FIG. 23 shows a side view of the mounting strip 3 from FIG. 22, and FIG. 24 shows a detail from FIG. 23 in an enlarged scale in the region of the connection between mounting strip 3 and mounting bracket 5. The mounting strip 3 has a groove 54 between the two support flanks 52, 53 of the mounting rail 6, said groove preferably extending in the longitudinal direction of the mounting strip 3 and preferably centrally thereto, which groove accommodates a head 55 of a connection means 56, in particular the head of a flat headed screw. In a state in which the mounting strip 3 is connected to the mounting bracket 5, the head 55 thereby does not extend into the region between the two support flanks 52, 53, and thus does not obstruct the attachment of the device 2.

In the embodiment, the mounting strip 3 has a sliding nut channel 57 between the two support flanks 52, 53, which channel extends in the longitudinal direction of the mounting strip 3. The groove 54 is positioned in the bottom area 58 of the sliding nut channel 57. When in the connected state, the head 55 of the connection means 56 does not extend up beyond the bottom area 58 of the sliding nut channel 57 or, respectively, does not extend into the sliding nut channel 57. As a result, even when the connection means 56 are mounted, it is also possible to introduce one or a plurality of sliding nuts into the sliding nut channel 57, in particular, into a section of the sliding nut channel 57 in a section of the sliding nut channel 57 delimited at both sides by connection means 56.

The width 59 of the groove 54 is less than 50% greater than the width of the head 55 of the connection means 56, in particular less than 25% greater and preferably less than 10% greater. The depth 60 of the groove 54 is less than 50% greater than the height of the head 55 of the connection means 56, in particular less than 25% greater and preferably less than 10% greater. The width 59 of the groove 54 is less than 90% of the width of the sliding nut channel 57, in particular less than 80% and in the embodiment, approximately 75%. The width 59 of the groove 54 approximately corresponds to the width of the opening of the sliding nut channel 57 facing the support flanks 52, 53. The depth 60 of the groove 54 is less than 150% of the depth of the sliding nut channel 57, in particular less than 100% and preferably less than 50%.

In the embodiment, the connection means 56 is a flat headed screw, which is inserted into a through bore 61 in the mounting strip 3 and screwed into a threaded bore of the mounting bracket 5. The through bore 61 may arbitrarily be introduced at a position in the mounting strip 3 that is suitable for the connection of the mounting strip 3 to the mounting bracket 5. To this end, the mounting strip 3 has a channel as a centering aid which is centrally positioned in the bottom area of the groove 54, which extends in the longitudinal direction of the mounting strip 3 and which preferably has a V-shape.

FIG. 25 shows a perspective view of the reverse side of the mounting system 1 from FIG. 1. On the reverse side, opposite the mounting rail 6, the mounting strip 3 has at least one locking strip 63 that extends in the longitudinal direction of the mounting strip 3, on which mounting rail additional components 64, 65 of the mounting system 1 may be directly attached by interlocking action or indirectly, through the use of adapter elements 66 that can be attached by interlocking action (FIG. 27).

FIG. 26 shows a side view of a mounting strip 3 from FIG. 25. The central region of the mounting strip 3 has two parallel locking strips 63 on the reverse side, the free ends of which project forward as compared to a connection strip 67 and thereby are adjacent to a groove 68 or, respectively, a receiving space, in which, for example, either the mounting bracket 5 can be inserted, or a connection element can engage, for example a connection element for connecting an additional component 64 to the adapter element 66. The locking strips 63 are integrally formed as a component of the mounting strip 3.

The locking strips 63 have a self-locking interlocking edge 80 (FIG. 32), in particular an interlocking 80 having an undercut 81. The two locking strips 63 extend spaced apart from one another, but parallel to one another in the region of the mounting rail 6 that is disposed on the front side. A first additional component 65 for bundling connecting wires 34, 35 that run on the reverse side of the mounting strip 3 belonging to the device 2 that is disposed on the front side is interlocked onto the locking strips 63, which component not only has a connecting section 69 that can be interlocked on the locking strips 3, but also has two cable guides 70, 71 for accommodating connecting wires 34, 35. The cable guides 70, 71 are symmetrical to a center plane, likewise as is the double-walled separating plate 72. The two cable guides 70, 71 are each accessible from the outside by means of two resiliently deflectable arms 73, 74, wherein the arms 73, 74 are disposed opposite one another and on the sides adjacent to the connecting section 69.

FIG. 27 shows a side view of a mounting strip 3 having an adapter element 66 snapped onto the locking strips 63. FIG. 28 shows a perspective view of the reverse side of the mounting strip 3 having two adapter elements 66 locked into place. The adapter element 66 preferably has a centrally disposed bore 75, which may be designed as a threaded bore or may have a rolled thread, an extruded hole, a press-in nut or the like, and one or a plurality of preferably eccentrically disposed additional bores 76, which may form a mechanical interface for attaching additional components of the mounting system 1 to the reverse side of the mounting strip 3. For example, the additional bore 76 may form a positioning means for the mounting of additional components, for example for the insertion of a corresponding positioning means on the additional component. The bores 75, 76 correspond to the receiving space 68, which is bordered by the adapter element 66, the two locking strips 63 and the connection strip 67.

FIG. 29 shows a second additional component 64 of the mounting system 1, in which said component is an additional bundling element for bundling supply lines 34, 35. The second additional component 64 is a double-tracked flexible wire part, which is affixed to the adapter element 66 in a clamping manner by means of a mounting element 77 that is screwed to the adapter element 66. By partially releasing the mounting element 77, the second additional component 64 is still retained, however can still be moved vis-a-vis the adapter element 66 along the two wire tracks that run parallel to one another, and subsequently can be clamped again so that it is possible to adjust the desired position of the second additional component 64 with reference to the adapter element 66 or, respectively, the mounting strip 3 that is affixed to the locking strips 63.

FIG. 30 shows a side view of the mounting strip 3 having a cable channel 78 locked onto the reverse side by means of the adapter element 66 on the mounting strip 3.

FIG. 31 shows a perspective view of an additional embodiment of a mounting system 101, in which at least one mounting strip 403 is connected at or near each of the two ends thereof to a vertical profile bar 4 by means of a connection element 79. In this case, the connection element 79 is formed from a section of a profile, out of which the profile bar 4 is also manufactured. Alternatively, another spacer may also be used, for example a profile piece having a smaller cross-sectional dimensions or also a rod that has been cut to length to achieve the desired spacing of the mounting strip 403 from the profile bar 4. The head 55 of the screw, by means of which the mounting strip 403 is connected to the connection element 79, is recessed in the groove 54 in the sliding nut channel 57.

FIG. 32 shows a side view of an additional embodiment of a mounting strip 503, which can be affixed to a profile bar 4 by means of a connection element 79. The connection element 79, which preferably has a square cross section, has an edge length that corresponds to, or is slightly smaller than the spacing between the two locking strips 63, so that the locking strips 63 form a guide through a positive locking when the connection element 79 is inserted into the receiving space 68 delineated by the locking strips 63 (FIG. 27). Even when another spacer is used instead of the connection element 79, it is advantageous when this spacer also exhibits positive locking with the locking strips 63, for example in the case of a distance rod that has a round cross section or rounded corners, when this spacing rod has two flattened sides that are positioned opposite one another, at least at the end sections of said spacing rod that are facing the mounting strip 503, the spacing between which flattened sides corresponds to the spacing of the locking strips 63.

As in the above described embodiments, the mounting strip 503 has a receiving device 120 for ordering means 8 or additional components 10 as well as a sliding nut channel 57 with a groove 54, however the mounting strip 503 does not have a mounting rail 6. Rather, the devices 2 are affixed to the mounting strip 503 by means of screws, which are screwed together with nuts that are disposed in, and can be slid in the sliding nut channel 57. The sections of the mounting strip 503 that can be mounted on then sliding nut channel 57 are flat at both sides, for example for an installation of the device 2 that is to be affixed thereto having a large contact surface area. The ends of the flat sections that face away from the sliding nut channel 57 are bent at a right angle and each form an enclosing receiving device 120, which receiving devices are set back as compared to the flat sections.

FIG. 33 shows a side view of an additional embodiment of a mounting strip 603, which can be affixed to a profile bar 4 by means of a connection element 79. The mounting strip 603 has a convex curvature on the front side thereof, wherein a mounting rail 6 is disposed at the position at the apex of the protrusion. While the mounting rail 6 and the sliding nut channel 57 with the groove 54 are symmetrical to a center plane 40, the profile of the mounting strip 603 is asymmetrical to this center plane 40. The second section 142, which is connected to the mounting rail 6 and terminates with the receiving device 120 on the one side, has a greater extension in the lateral direction than the second section 242 on the other side, which is connected to the mounting rail on the other side. By contrast, the vertical distances 44 covered by the two sections 142, 242 coincide.
